"For example, I am sure it is not possible in Germany because tenancy contracts that include short-notice eviction clauses are void." Dutch rent law is stricter than German and it's still allowed. It's a combination of a regulatory framework at a higher level, and anti-squatting not being 'renting' but 'borrowing'. (terminology is a problem here since there is no word in English for the civil law legal form that is used. The closest is 'lease' but that is used for regular renting already in English.) More to your point, it certainly exists in Germany, and is generally called "Hauswachter" (that is, the people living there, not sure about the form itself). Companies offering it are for example http://de.cameloteurope.com/ http://de.cameloteurope.com/ .
